Summary
Complete urinary function recovery is possible even after delayed decompression for cauda equina syndrome (CESR) due to lumbar disc herniation (LDH). While longer delays slow recovery, they do not impact the extent of recovery, emphasizing timely surgical intervention.
Area of Science:
- Neurosurgery
- Urology
- Spinal Surgery
Background:
- Complete cauda equina syndrome (CESR) secondary to lumbar disc herniation (LDH) often necessitates surgical decompression.
- Delayed decompression in CESR raises concerns about the potential for permanent urinary dysfunction.
Purpose of the Study:
- To evaluate urinary function recovery following delayed decompression in CESR due to LDH.
- To identify factors that predict urinary recovery in these patients.
Main Methods:
- Retrospective study of 19 patients with CESR due to single-level LDH, all treated beyond 72 hours.
- Urinary outcomes assessed using ordinal and dichotomous scales; logistic regression and Spearman correlation used for analysis.
- Mean delay to decompression was 11.16 days; mean follow-up was 31.71 months.
Main Results:
- Optimal urinary recovery observed in 73.7% of patients.
- Time to full recovery was moderately correlated with delay in decompression (r=0.580, p=0.030).
- Mean recovery time for optimal bladder recovery was 7.43 months; other factors did not significantly predict outcomes.
Conclusions:
- CESR is not a point of no return; urinary function can recover even after delayed decompression.
- Longer delays correlate with slower recovery but not the final extent of recovery.
- Early surgical decompression is still recommended to optimize recovery time.
